A concentration index is a scaled covariance between an outcome and rank in the distribution of socioeconomic status. Adjusted for age and sex. Concentration curves presented in Supplementary Fig. 1. The concentration index for hypertension prevalence is estimated for the full sample, and the others are estimated for those with hypertension
